If the gun will break open 1/8" like you say, take a flashlite, and peek down in there. My guess is it is hanging up on the firing pins. You should be able to push them back in with a screwdriver or whatever you can fit in there. DON'T FORCE ANYTHING!!!!!!! If you can't figure it out yourself, take it to a COMPETENT smith. Those little guns are bringing good money these days, well worth whatever it costs to repair. Or you could just sell it to me. lol. If you see the firing pis sticking out, you coud also try pushing them in from the end of the barrel with a piece of round stock.
